2 OFF Wait for Motor Start/Stop Command
The starting method of the disk drive spindle motor may be
adjusted by by the setting switch on the IDD. If this switch
is set to inhibit motor start control, the spindle motor starts
immediately after the IDD is turned on. If the setting switch
is set to enable motor start control, the motor does not start
if the IDD is turned on. In this case, a command is used to
start the spindle motor.

There are three possible installation directions, and the mounting
angle must be 5* from the horizontal.
Dont install the PCA on the top!
Ambient temperature
-------------------
The operating temperature range of the drive is specified at a dis-
tance of 3 cm from the drive. Note, temperature specifications are
for the outside air surrounding the drive.
Make shure to maintain the base temperature range of DE from 5*C to
58*C.
Multi-drive connection
----------------------
Host systems, IDDs, and other SCSI controllers can be connected
(daisy-chained) to SCSI provided that the total number of SCSI de-
vices connected does not exceed eight.
Cable requirements
------------------
A characteristic impedance of 100 10% is recommended for the un-
shielded twisted-pair ribbon cable. Characteristic impedance greater
than 90 is preferred for the shielded cable. A minimum conductor
size of 28 AWG shall be employed. It is recommended that the shielded
cable be uses for connection outside the system cabinet.
To minimize discontinuities and signal refelections, cables of dif-
ferent impedance should not be used on the same bus. The maximum
cable length is 7m. A cable length of 1m or more is recommended be-
tween SCSI devices.
Terminator
----------
Terminator is already installed in IDD at shipment. Remove the ter-
minator if the IDD is not installed at beginning or ending position
of SCSI cable. The terminator is only installed on the controller
PCA when the IDD is connected to the beginning or ending position
of SCSI cable.
External LED Connection
-----------------------
The user can connect the external LED to the drive if necessary. The
external LED is connected to CN6 on the PCA.

Tips & Hints about ICP controllers and other peripherals
========================================================
Tagged queues and Fujitsu M 26xx harddisks
------------------------------------------
Fujitsu Harddisks of the M26XX series do not support the SCSI-II
feature tagged queues. You should disable this feature in the
initialize disks menue of the GDTSetup program. An inquiry command
shows, that the harddisk supports tagged queues (this is why you can
enable it in the GDTSetup) but this is not true as stated by Fujitsu
Germany.
